Want to leave that bulky old TI-83 calculator on your desk? You can run a TI-83 emulator on Windows, Mac, and Android that functions just like the real calculator, except faster. That's because the emulator is using the actual TI-83 code in the form of a ROM file. You can have your calculator replacement up and running in just a couple minutes.

Download Wabbitemu. This is one of the newest and most powerful TI-83 emulators available, and can run on Windows, OS X, and Android.

Download a TI-83 ROM file. A ROM is a file that contains the system image of the calculator. The Wabbitemu program does not come with a ROM for legal reasons. You can follow the prompts in the Wabbitemu setup program to create your own ROM from your own TI-83, or you can download one from a variety of locations online.

To find a TI-83 ROM online, simply search Google for "ti-83 rom" and select a result. Avoid sites that are laden with advertisements or that ask you to download extra files or programs. The ROM file will have a .rom extension.
